Problem solving

# Problem-solving Investigations - Year 2

The problem-solving investigations below match Hamilton’s weekly maths plans. We now also provide Year 2 maths as short blocks. We will eventually be phasing out the plans, as we believe our short blocks offer you all of the same advantages and more, including the integration of the problem-solving investigations into each unit of study. Find out more about the advantages of Hamilton's short blocks.
